(3,4) And they can bind to erythrocytes,simultaneously with immune factors, causing hemagglutination and anemia. (5)Of the 119 known dietary lectins, about half are panhemagglutinins, clumping allblood types. The remainder are blood-type specific.
Two of the four cells will contain one recombinant chromosome. In eukaryotic cells, crossing over can also occur during mitosis. Somatic cells (non-sex cells) undergo mitosis to produce two distinct cells with identical genetic material.
Crossing Over. During meiosis, when homologous chromosomes are paired together, there are points along the chromosomes that make contact with the other pair. This point of contact is deemed the chiasmata, and can allow the exchange of genetic information between chromosomes. This further increases genetic variation.
